An El Salvador immigrant who was accidentally expelled and then taken back to the US after a lawsuit battle, claimed that they were hit and submitted him to psychological torture during his imprisonment in his country, according to court documents submitted by his lawyers.

Kilmar Abrego Garcia, aged 30, who has been imprisoned in the US where he is accused of transporting irregular immigrants, spent many months in a highest security prison in Salvador, after departing with more than 250 men, for most of whom were suspected.

His case became emblematic of the confrontation between federal justice and Donald Trump’s government focusing on the US president’s policy of mass deportations.

Donald Trump has taken the battle against irregular migration as his absolute priority and frequently communicates the issue of expulsion of immigrants.

Abrego Garcia “suffered severe abuse of arriving at Cecot (Terrorism Confinement Center- Terrorist Restriction Center), including violent blows, sleep deprivation, inadequate nutrition and psychological torture,” his lawyers told a document. Salvador, who is married to an American.

They argued that during their arrival “he and another 20 nationals El Salvador were forced to stay on their knees from 21.00 to 06.00, with prison officials hitting those who collapsed from fatigue”. During this time “he was not allowed to go to the toilet and he got dirty”.

Prisoners were led to crowded cells without any window and artificial lighting 24 hours a day, according to lawyers who also say that their client lost 14 pounds, in the first two weeks of his detention.

While he is currently being held in Tennessee (south), where he is being prosecuted for immigrants, Kilmar Abrego Garcia called for, at the end of June, to remain in prison for fear of being re -deported after his release.
